Steam baseboard

ABSTRACT

Design the device Steam baseboard to use for steam heating. Water is not easy to get out and water creates the noise and does not easy to get out of the system. Water prevents the heating. We convert the hot water heating baseboard to steam baseboard by using the John&#39;s pipe and John&#39;s effect.

We understand that hot water heating baseboard is very pretty andeconomical. The pipe can Stand the pressure 30 psi up to 100 psi. Can weuse this hot water heating baseboard to be used for steam heatingradiator? I have this question. All my friend told me that you can notuse the hot water baseboard for steam baseboard because the noisegenerated by the condensation water. We discover that the pressuredifference prevent the condensation water to flow downward even with apitch. This pressure difference is generated by steam condensation overthe radiator. See diagram 1. This effect is named John's effect. We canapply this effect to solve the water drain problem. We hate the oldstyle cast iron radiator is so heavy and ugly. It also occupies too muchspace.

I design the new device to solve those drain problem. I utilize thepressure drop between the primary steam pressure and secondary pressure.I add the extra pipe to create the primary pressure. This extra pipe isnamed John's pipe. This effect pressure drop due to the John's pipe isnamed John's effect like diagram 2. Because of this John's effect, thepitch is not needed to drain the water out of the system. We can utilizethe hot water heating baseboard with adding the John's pipe and airvalve like diagram 2. The length of the baseboard can be varied from 2feet to 16 feet. The air valve is need here to push the air out of thesystem. The added pipe can be varied from ⅜″ to ¾″ in diameter.

We also propose to improve the old cast iron steam radiator (see diagram3) by adding John's pipe see diagram 4. The old cast iron radiator is soheavy, not pretty and space wasted. I prefer the hot water baseboardheating. By adding the John's effect, we can convert hot water baseboardheating equipment into steam baseboard heating equipment.

The advantage of this conversion has many issues as the following. 1.The copper tubing is cheap compared with cast iron is 1:5 ratio.

2. It is light. It is very easy to install. Less man power.

3. The heat transfer is fast for the copper tubing. 4. It is pretty, andeasy to decorate the house.

5. We can mount the baseboard heating along the wall. It saves thespace.

6. It is easy to apply zone valves to control the room temperature andfloor temperature.

The new design needs no pitch, and can be mounted along the wall andsave the needed space for the modern house.

The old cast iron radiator needs 6% pitch to drain the water. Seediagram 3. The old cast iron radiator can be improved with John's pipeand gets John's effect, and needs no pitch to drain water. See diagram4.

1. Add the extra pipe to provide the primary boiler pressure of hotwater heating baseboard
 2. The John's effect can be used in many othercases.
 3. Add the half inch pipe directly to the old radiator fromentrance to the other end in order to provide the primary pressure topush the water out of the radiator.
